My fiance and I already ordered save the dates, My mother and grandfather (her father) are not getting along at all right now. This is a common thing. They will get into a really bad fight then eventually make up after weeks or months. My mother is now saying if I invite him she won't come to my wedding. My mother is one of my best friends so I would be devastated if she did not attend my wedding. Should I not send him a save the date and if they are getting along when my invitations are due then just send him an invitation? What do you guys think?
